First of all I would like you to tell me what does it mean to change WFP driver type in settingsMaybe I'll need to take a look at this, seems strange that you've got the same problem in v6.
Could you please tell me more about your computer configuration?
Which AV do you use? Maybe a Firewall app or something like that?
What you describe is looks much like WFP drivers incompatibility. So we should understand what WFP drivers do you have installed besides Adguard's.
I got Eset Smart Security and Malware Bytes Antimalware both last version + Eset is my firewall
I made sure to add the whole folder of AdGuard and the Exe it self to the exception list on both programs
I am using Edge Browser + Windows 10
I am using the default Adblock List + Easy List that it + I am Not using Adguard assistant or Web of trust extensions
